How does evapotranspiration happen?
Evapotranspiration is the combined process of evaporation and transpiration. Evaporation occurs when water from soil and surface bodies, like lakes and rivers, turns into vapor due to heat from the sun. Transpiration involves the release of water vapor from plant leaves through small openings called stomata. Together, these processes contribute to the movement of water from the soil and plants into the atmosphere.
Is splash erosion more powerful than gully rill and wave erosion?
When the sun heated the soil surface and soil does not have any water. when rain drops hit the surface of soil it cause the soil eroded.
What is the movement of surface water into rock or soil through cracks and pore spaces?
percolation
When an earthquake where is the greatest motion felt on the surface?
Right at top of the epicenter, the greatest shaking felt. It also depend on the types of soil. If the soil is soft then the intensity is amplified and where the soil is hard the intensity is damped.
Why do earthworms bring piles of soil to the surface?
The piles of soil are the worm casts, (faeces) which the worm excretes after feeding. These may be pushed to the surface as the worm clears out his tunnel or deposited on the surface as the earthworm feeds above ground. As the worm will not venture far from its burrow it might explain as why they are situated around the opening of the hole.
What is soil evaporation?
Soil evaporation is the process by which moisture from the soil surface is converted into vapor and released into the atmosphere. This occurs primarily due to heat from sunlight, which warms the soil and promotes the transition of water from liquid to vapor. Factors such as temperature, humidity, wind speed, and soil moisture levels influence the rate of soil evaporation. It plays a crucial role in the water cycle and affects plant water availability and soil health.
What is the first stage of evaporation?
The drying of soil due to surface residue.
What type of irrigation loses the most water to evaporation?
Surface irrigation loses the most water to evaporation because water is applied directly to the soil surface where it is exposed to air and sunlight, increasing the likelihood of evaporation.
Which has no control whatsoever on the thickness or type of soil that will form in any surface environments?
The intensity of sunlight has no direct control on the thickness or type of soil that will form in surface environments. Soil formation is primarily influenced by factors such as parent material, climate, living organisms, topography, and time.
What prevents excess evaporation of water?
Factors that prevent excess evaporation of water include high humidity levels in the air, the presence of a water-impermeable covering (such as mulch or dense vegetation) on the soil surface, and cooler temperatures that reduce evaporation rates. Additionally, windbreaks or structures can help reduce wind exposure, which can increase evaporation.
What factors control the infiltration capacity of the soil?
1- Physical characteristics of the soil 2- how much moisture is already in the soil 3- the type and extent of the vegetation cover 4- the slope of the surface 5- nature and duration of the rainfall
How does moisture leave the soil?
Moisture leaves the soil through processes such as evaporation, transpiration from plant roots, and drainage. Evaporation is the direct loss of water to the atmosphere from the soil surface, while transpiration involves plants absorbing water from the soil and releasing it through their leaves. Drainage occurs when excess water moves through the soil and eventually flows out of it.
Is there any evaporation at night?
Yes, evaporation can occur at night, although it is generally slower than during the day due to lower temperatures and reduced sunlight. Factors such as humidity, wind speed, and surface temperature can influence the rate of nighttime evaporation. Even in cooler conditions, moisture can still escape from surfaces like soil, water bodies, and plants.
What factors influence soil moisture?
Factors that influence soil moisture include precipitation, temperature, evaporation rates, soil composition, and topography. Other factors such as vegetation cover, drainage patterns, and human activities can also impact soil moisture levels. Ultimately, the balance between water inputs and outputs in the soil determines its moisture content.
The amount of surface runoff increases as?
A number of factors. Soil saturation is one.
Does humidity add moisture to soil?
ofcourse.humidity add moisture in the soil......
What kind of surfaces do evaporation happen at?
Evaporation can happen on any surface where liquid water is exposed to air. This includes surfaces like bodies of water, soil, plant leaves, and even wet clothes or dishes.
